Abstract: A concentric pulley drive assembly is disclosed as having a central pulley mounted to a motor axle and rotatably driven therewith by a drive motor. A partial pulley in the form of a partial annulus is positioned about a portion of the periphery of the central pulley concentrically with respect to the motor axle. A tape strip coupling the two pulleys transmits torque from the central pulley to the partial pulley to induce annular rotations of the partial pulley about the motor axle commensurate with the annular rotation of the central pulley. An antenna or sensor support platform is coupled to the extremities of the partial pulley for pivotal positioning about the motor axle in conjunction with the annular rotation of the motor axle.
Abstract: A ball locking mechanism for the releasable locking of a movable part comprises a locking or arresting ball arranged in at least one bore of a stationary or fixed part or component and can be pushed, by means of a slide member, into one of a number of bores of the movable part or element, so that such movable part can be locked in place. For unlocking, the slide member is displaced until a bore thereof comes to lie essentially coaxially with respect to the remaining bores. Then, the ball moves out of the aforementioned one bore of the movable part. The movable part can then be displaced until a further similar bore thereof comes to lie essentially coaxially with respect to the bore of the fixed part. By means of the pressure of a spring, exerted upon the slide member, the ball then is again pushed into this further bore.
Abstract: The invention resides in an outside door handle assembly which comprises a door handle pivotably mounted on a door of an automotive vehicle; and a door latch operating rod having an end portion which is pivotably attached to an extension of said door handle after assemblying thereto. A pair of finger projections are made integral with the door handle arm. There is provided a channel-shaped metal bracket fixedly attached to a door panel and pivotably mounting said finger projections. An inclined groove formed on each of the finger projections generally opening towards the two limbs of the bracket and adapted for receiving partially these limbs when said door handle arm has been brought into its upper service position, thereby torsional deflexion of the bracket as liably occuring during the door-opening operation being prevented effectively.

Abstract: An overload coupling includes at least one latch plunger housed in a holder or in a coupling member, fits in a recess of a second member to establish connection. The plunger has or is part of a hydraulic system and can be forced out of the recess upon overload against the hydraulic pressure in the system and, in some instances, with the aid of centrifugal forces. The plunger and holder can be part of a unit that is releasably fastened in the coupling member and set to trip upon torque exceeding a predetermined level on the coupling member. Also, the plunger can have internal ducts or external conduits that include a pressure relief valve, as well as a spring return, which can effect connection upon reduced speed when centrifugal force factors are reduced. The pressure in the system can be set remotely with a piston that is spring loaded. In one variation, the coupling can be within a planetary gear system that establishes driving connection from an input to an output via planetary and sun gears.
